Burst |

The burst parameter can be very interesting. It allows the class to send, for a small time, as many packets as the link allows. This can be very interesting for a class that holds http traffic. If you have a class with 10kbps and a burst of 50k, it will load small pages very quick. After 50k, the burst is used and the rate will drop to 10kbps.
The same story goes for ceil and cburst. But most of the time, you don't want the class to send more packets then it's ceil allows. So removing the cburst is a good choice for that case. There is also a minimum burst and cburst. It depends on the hardware timer. For 10Mbit on i386 this is 12kb. If you don't specify the burst and cburst parameter, htb will calculate the smallest one. stef.coene@docum.org | |
